Example Embodiment
[0019] Example 1:
[0020] A method for indoor rapid cultivation of wild barley includes the following steps:
[0021] 1) Remove the seeds of wild barley, select uniform seeds and treat them at -20℃ for 48h. After washing the wild barley seeds with distilled water, use 100mg / L gibberellin to germinate the seeds at a low temperature of 0-4℃ Pretreatment
[0022] 2) The pre-treated wild barley seeds obtained in step 1) are simply rinsed with distilled water, and then evenly sprinkled on the seed rack of the seed germination box for germination. The nutrient solution in the germination box is a nutrient solution containing 5mmol / L NaCl; for germination The indoor conditions are 24 / 18℃, dark, and wild barley seeds can germinate after 3 to 5 days, and the germination rate can reach 82%;
[0023] 3) Change the seedlings obtained in step 2) to light culture, 25℃, 16h light and 16℃, 8h without light, alternately, the light intensity is 600μmol / (m 2 ·S), the culture medium is hydroponics, an...

[0027] Example 2:
[0028] An indoor rapid cultivation method for wild barley, the steps are the same as in Example 1, except that the relevant temperature and NaCl concentration are adjusted, and it mainly includes the following steps:
[0029] 1) Remove the seeds of wild barley, select neat seeds and treat them at -18℃ for 48 hours. After washing the wild barley seeds with distilled water, use 150mg / L of gibberellin for seed germination at a low temperature of 0-4℃ Pretreatment
[0030] 2) The wild barley seeds obtained in step 1) are rinsed with distilled water, and then evenly sprinkled on the seed rack of the seed germination box for germination. The nutrient solution in the germination box is a nutrient solution containing 10mmol / L NaCl; for germination The indoor conditions are 26℃16h / 16℃8h, dark, the wild barley seeds can germinate after 3 to 5 days, and the germination rate can reach 85%;
[0031] 3) Change the seedlings obtained in step 2) to light culture, 24℃, 16h light ...

[0035] Example 3:
[0036] An indoor rapid cultivation method for wild barley, the steps are the same as in Example 2, except that the relevant temperature, time and NaCl concentration are adjusted, and it mainly includes the following steps:
[0037] 1) Remove the seeds of wild barley, select neat seeds and treat them at -16℃ for 24 hours. After washing the wild barley seeds with distilled water, use 200mg / L of gibberellin for seed germination at a low temperature of 0-4℃ Pretreatment
[0038] 2) The wild barley seeds obtained in step 1) are rinsed briefly with distilled water, and then evenly sprinkled on the seed rack of the seed germination box for germination. The nutrient solution in the germination box is a nutrient solution containing 15mmol / L NaCl; for germination The indoor conditions are 20℃16h / 16℃8h, dark, the wild barley seeds can germinate after 3 to 5 days, and the germination rate can reach 80%;
[0039] 3) Change the seedlings obtained in step 2) to light culture, ...
